The solid salt become a solute: ions Na+ and Cl- exist now in solution.
The water becomes a bit opaque and translucent
Firstly, pure salt is white and it becomes colourless when dissolved in water. Secondly, solid salt is a non-conductor of electricity, whereas the solution is an electrolyte and conducts well.
don't know look in your science book
Yes it is. Chemical property
The chemical composition of sugar remains the same when dissolved in water. Only the physical state of sugar changes, from solid to liquid. The total amount of matter in the system (sugar + water) also remains constant.
solvation
will change the boiling and freezing point of the water
Solubility is considered a physical process.
Some salts dissolved in water have an acidic pH.
The physical properties of water can change when a compound is dissolved in water. The dissolved compound will determine which properties change. Some will change the surface tension, others will change the pH. Many changes are possible.
Yes, the apparent shape of sugar changes when dissolved in water. Sugar in its solid, crystallized form is a cube. When dissolved in water, the individual molecules separate, and the crystalline structure breaks down.
Dissolved solute (NaCl, salt) will raise the boiling point and lower the freezing point of water. This is known as a colligative property.
